“If you leave us at 450ppm for long enough it will probably melt all the ice – that’s a sea rise of 75 metres. What we have found is that the target we have all been aiming for is a disaster – a guaranteed disaster,” Hansen told the Guardian.

“The damaging effects of climate change are accelerating. James Hansen of NASA has screamed warnings for 30 years. Although at first he was dismissed as a madman, almost all his early predictions, disturbingly, have proved conservative in relation to what has actually happened.”

Actually among sensible people he is still dismissed as a madman. It’s true he predicted continued warming and the planet continued to warm, at least up until around 1998. Just no where near as much as he claimed it would, especially in his later predictions. Had someone predicted global cooling back in the ’80’s and had it cooled a bit afterwards, no doubt that or those scientists would have been viewed by some as geniuses today.

I’d like to coin the term “Slow Motion Tsunami” to describe Hansen’s prediction of sea level rising and copyright it here. When he writes a book with that as it’s title, I’ll make a motza from the doofus. Seriously though, he must be thinking “Why is my hypothesis not working?”

“What we have found is that the target we have all been aiming for is a disaster – a guaranteed disaster”

I wasn’t aware that humanity (the implied ‘we’) has been ‘aiming’ for any specific CO2 level. I am aware that Hansen & company (the actual ‘we’) have built careers on the the hopes that there would be ‘a guaranteed disaster’. The actual disaster is going to be what happens to the climate alarmists when their acolytes realize that their standard of living is declining to no purpose.
